Connect to GND.
Serial digital differential input.
No Connect. Not bonded internally.
External AGC capacitor.
Connect pin 5 and pin 6 together as shown in the Typical
Application Circuit on page 13.
Forces the Equalizing and DC RESTORE stages into bypass mode
when HIGH. No equalization occurs in this mode. (Internal
pull-down).
Squelch Adjust.
Adjusts the approximate amount of cable equalized before CD goes
low. See Section 4.4 and Section 4.5. (Internal pull-down).
Equalized serial digital differential output.
